navigator

问题 I'm putting together this Ask/Answer App, and came across this hurdle: I want to trigger a function in a scene from the navigationBar. Similar to a Login app I have a button in the NavigationBar to Submit an answer: RightButton(route, navigator, index, navState) { if (route.name=='TextInputView'){ return <TouchableHighlight underlayColor="transparent" style={{ marginRight:13, marginTop:0}} onPress={() => this.refs.TextInputView.submitSolution()}> <Text style={ styles.leftNavButtonText }>Done<

问题 My app has 3 categories of buttons, I want to have a tabbed panel I can use to switch between the 3 categories like in this example: My app is a mobile app though so I can't use mx components. When I try searching for mobile tabbed navigation etc., I come up with only viewnavigator examples. 回答1: For a mobile tabbed application, you simply use the TabbedViewNavigatorApplication class: FIRST METHOD Your views are simply MXML components that use <s:View> as the root note. Reading your comments,

问题 I'm using Navigator with jqGrid and I'm repeating over and over settings such as: savekey: [true, 13], closeOnEscape: true, closeAfterAdd: true How can I define these settings globally to all my grids on current page? I know how to specyfiy jqGrid settings globally, but I have problems with Navigator. My sample Navigator definition looks like this: $("#dictionaryElementsGrid").navGrid( "#dictionaryElementsPager", { search: false, edit: true, add: true, del: true }, { // Edit options: savekey:

问题 I have attempted to combine the usage of React Native Navbar & React Native Router Flux to simplify the make of my RN app. In doing so, I have gotten to a point at which I am switching routes via React Native Router Flux until after I get to the home page, in which I need to use Navigator again. The reason being is that I don't think it is yet possible to create something like this with React Native Router Flux. What I am trying to do is create a simple transition from the login/signup page

问题 I've been stumped for a while with RN Navigator trying to figure out why Navigator renders all the routes pushed in its stack. Initially <Navigator initialRoute={{name:"Route 1", index: 1}} /> Then upon issuing a navigator.push({ name : "Route 2", index: 2 }) the render() method of my component gets called which re-renders Navigator, which in turn calls renderScene . After pushing the 2nd route and logging the route when renderScene gets called yields to: Render() --> renderScene(), {name:

问题 After several tests in this scenario, I have some questions that I can not answer my self, so I ask for help to clarify my concepts. Provider vs props in Navigator What is the difference and what is the best approach to setup the Navigator and pass store to different Scenes of a React Native app export default class App extends Component { render () { return ( <Provider store={store}> //<-- here <Navigator style={{flex: 1}} initialRoute={{ component: MainContainer }} //<-- here renderScene={

问题 I am using jquery-ui-maps and HTML5 geolocation to show to the user a list of locations and I need to leverage the user's geolocation. So, here is the use case, User does not have GPS/Location Services enabled. User opens the application and navigates to the view that calls navigator.geolocation to get the user's position The app errors out and notifies the user they must enable GPS/Location Services The user then navigates out of the app and enables GPS When the user comes back to the app

问题 The navigator object has a javaEnabled function that indicates if the browser has javascript support. This seems to be a little odd: If JS is indeed enabled the function will return true, well obviously. If JS is disabled it will return < nothing > since it is never run, javaScript is disabled. I must be missing something here, or is it really that useless this function? 回答1: java != javaScript navigator.javaEnabled checks for the presence of Java , not JavaScript. Reference This must be a

问题 I have a big problem. I want to use navigator and sliding menu. Then I need to have some behaviour on postpush. This is my codepen example: http://codepen.io/anon/pen/zxgpVo If you stay in Home and navigate from this point, then you see the console.log . But if you change from the sliding menu and go to Products, then the console.log doesn't working and if you return in Home doesn't working here anymore. I create 2 navigator with the same name. This is a right thing? Maybe this can be the
